Types of Hazardous Waste
An item is considered waste when the owner determines that the material is no longer useful and needs to be discarded. A detailed description of the wastes generated at the University is in the Waste Analysis Plan .
An item is considered to be hazardous waste if it meets one or more of the following characteristics:
- Mixture contains a listed hazardous waste and a non-hazardous waste.
- Material meets the definition of one of the following:
- Ignitability (flashpoint < 60oC or supports combustion)
- Reactivity (e.g., water reactives, cyanides, explosives, unstable chemicals)
- Corrosivity (ph < 2 or > 12.5)
- TCLP toxicity (e.g., pesticides, heavy metals, organic compounds, see Waste Analysis Plan, Attachment B .)
- Material is listed in 40CFR 261, Subpart D, (see Waste Analysis Plan, Attachment B .)
- Material is not excluded from regulations.
Individual departments are responsible for properly identifying the hazardous waste they generate and for following University disposal procedures. Departments should contact the EHSRM office for assistance if necessary to characterize hazardous waste through process knowledge or chemical analysis.
